This is truly the greatest serum of all time. I’ve never experienced anything like this. My skin is hydrated, dewy, plump, and feels so smooth. I’ve taken care of my skin over the past 10 years but at 31, between kids and work, I’ve noticed a little less of that youthful glow. This certainly brought it back. My only complaint is that the size is so dang small. I’ve had it for about a month and I’m almost out.

Excellent serum for combo skin

I love that this serum is great for combination skin. It soaks in easily and doesn't leave a residue.

Excellent product

This is liquid gold! I have combination skin while also fighting fine lines . This serum soaks in immediately and I compliment it with the Undaria Argan Oil this equals perfection of glowing dewey skin. I highly recommend.

Love this Sea Serum

I use this sea serum daily with my hyaluronic serum. Perfect after a long beach day to treat dehydrated skin as well as daily use.

Serum

I’ve used the Osea products for years, I use the blemish balm and the algae oil daily !!!!! But I just tried this for the first time! I put it on and the blemish balm after. I think my skin feels great and I love the way it feels. It soaks in and hydrates and my skin just feels great, I think the price is high considering the bottle is so small but non the less I love it and I love their products :)

Vitamin Sea Serum

The website states that the vitamin sea serum is fragrance-free, however, it does have a mild scent upon application that fades within a few minutes. I found that one full pump was sufficient to cover my entire face, ears, front and back of the neck, and decolletage. The product gave my skin a nice glow. However, I do not think that it lived up to moisturizing my skin. As previously stated, I did not use an OSEA Malibu brand moisturizer cream during this testing. Nevertheless, I have used other serums that provide both brightening and moisturizing effects. After three days of only using OSEA Malibu, my skin felt very dehydrated and I decided to incorporate these products in addition to my regular skincare routine. The website does state to follow with a moisturizer, but I would prefer to use a serum that has double-duty. The OSEA Malibu essential hydrating oil most likely would have been a good addition to this routine.
